Working of PNP transistor HD

This Video contains the working of pnp transistor. Here emitter base junction forward bias & collector base junction reversed bias. So that we can get collector, emitter and base current. Thus, in pnp transistor is carried by holes & at the same time their concentration is maintained. But in the external circuit the current is due to flow of electrons.
